Appbar covering items in recyclerview at the top with scrollFlags

At the top, not moving When scrolling down,or just scrolled down and not moving When scrolling up from the bottom

Hi, I've tried to add the app bar hiding behavior. If I try to scroll down everything is fine, it works how it's supposed to. If I'm at the bottom of the list and scroll up a little bit it's also working great. However, when nothing's moving and I'm at the top, the app bar is covered by items in the recycler view.

The only problem now is the items covering the app bar.
